description
The TM2EP64DPN is a 16M-byte, 168-pin, dual-in-line memory module (DIMM). The DIMM is composed of
eight TMS427809A, 2 097 152 byte × 8-bit 2K-refresh EDO DRAMs, each in a 400-mil, 28-pin plastic TSOP
(DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS427809A data sheet (literature
number SMKS887). The TM2EP64DJN is available with an SOJ package (DZ suffix).
The TM2EP72DPN is a 16M-byte, 168-pin DIMM. The DIMM is composed of nine TMS427809A,
2 097 152 byte × 8-bit 2K-refresh EDO DRAMs, mounted on a substrate with decoupling capacitors. See the
TMS427809A data sheet (literature number SMKS887). The TM2EP72DJN is available with an SOJ package
(DZ suffix).
The TM4EP64DPN is a 32M-byte, 168-pin, dual-in-line memory module (DIMM). The DIMM is composed of
sixteen TMS427809A, 2 097 152 × 8-bit 2K-refresh EDO DRAMs, mounted on a substrate with decoupling
capacitors. The TM4EP64DJN is available with an SOJ package (DZ suffix).
The TM4EP72DPN is a 32M-byte, 168-pin DIMM. The DIMM is composed of 18 TMS427809A, 2097152 × 8-bit
2K-refresh EDO DRAMs, mounted on a substrate with decoupling capacitors. See the TMS427809A data sheet
(literature number SMKS887). The TM4EP72DJN is available with an SOJ package (DZ suffix).
